A national Muslim civil rights group that's been active in Middle Tennessee has regained its tax-exempt status.

The Washington, D.C.-based Council of American Islamic Relations and its related foundation were two of about 275,000 nonprofits that lost tax-exempt status last year for not filing tax returns for three years in a row. On June 23, the IRS sent a letter to the CAIR-Foundation Inc., saying that the nonprofit is now tax exempt.

Internal Revenue Service officials confirmed Thursday that group — known by its acronym CAIR — is tax exempt.
